I wouldn't recommend the sidestand pivot, especially if you've done the sidestand mod... Even assuming the sidestand was made of unbreakium alloy, you could drop it, the stand could poke through the floor (I don't know what your parking area is like) or it could slide and...you could drop it!
I park in a narrow slot in an underground garage. I pull in, do a slow speed U-turn and basically line up to the slot. I normally then kill the engine and just walk it backwards while I'm still in the saddle. When I leave I just ride straight out. I don't see why you would ever need to do an Austin Powers type of turn.
I used to park my 1200 Bandit in a shed. There was a small slope leading up to the door so I rode straight in. When exiting I would just back the bike straight out, using gravity and the brakes to control it (same as off-loading from a trailer) until I rolled it out to the street where I would start it up and finish putting my gear on.
